The Waters Spherisorb ODS2 HPLC column 250x20mm, 10µm, is based on an octadecylsilyl phase (other designations: ODS, RP-18, C18) on spherical silica and is mainly used in reversed-phase chromatography. Spherisorb ODS2 is a more heavily endcapped C18 variant with robust reversed-phase performance and good reproducibility compared with ODS-1. Areas of application for the Waters Spherisorb ODS2 are routine RP analysis, pharmaceuticals, impurities, food and environmental samples.
The Spherisorb series is based on mechanically robust silica with a pore size of 80 Å and is available in several particle sizes. ODS1 has a lower ligand density and lower carbon loading, while ODS2 offers a more densely packed, end-capped C18 surface. The series is complemented by short alkyl chains, cyano, phenyl, amino, and silica phases, as well as strong anion- and cation-exchange phases. This allows for the coverage of a wide range of classical HPLC methods using a silica base that is consistent across the product family.
